The other site is down so I'm hoping some GP guys are floating around here. I'm having an issue with my hvac controls. I have the 3-knobber setup. I can't seem to find a decent looking replacement locally, but came across the newer style (01-03) manual controls with the two sliders in the middle for dual zone heat that looks to be in good shape. The connections on the back look identical to the 3 knob setup. I was wondering if I could just swap them out and just run it as a single zone?
